This is a type stick for using an HHKB in the "Sonshi" style (a specific typing style). I just bought it, but I don't use it much, so I'm selling it. There are no noticeable scratches, and it's in good condition. I threw away the box, so I will only ship the item itself as shown in the photos. As of December 31, 2025, it's 2,480 yen on Amazon.
